CANADA VAWT Model FF01

CANADA-VAWT is a Flip-Flop type Vertical Axis Wind Turbine which works purely on Drag principle. Although at present it is at prototype stage, its development is at final stages.
From its conception in the early 80's (Cardboard model) to now an almost working model, its performance has strengthened the confidence that it can be successful as a roof top wind turbine as well as a large scale power generator.
True it has a 'lot' of moving parts i.e. the flaps, but the RPM is very low max around 60 rpm max. This prevents these moving parts from being overstressed. Our flap design has withstood the harsh Canadian winters as well as some of the hot summer days since about two years without falling apart, breaking or deforming beyond correction.
There is a lot to be said about the design of its GUTS where, in my opinion, the actual success or failure lies. Many iterations of generator design and implementation strategies have been considered and carried out so far. The current one, I think will establish a direction to last for a while...

Thanks for your comment. In this prototype, corrugated plastic sheets have been used. Although it is not completely silent i.e. you can hear light slapping type of sound at higher winds if you are in the vicinity or if you have open windows, however, the power gain versus the sound db level is a compromise worth considering.

This prototype has been working in a residential backyard in this particular configuration about a year or so. There have been no concerns raised by any of the neighbors.

Yes, that works, but its hard to make it silent, this way..
